SPECIFICATION forming part of Letters Patent No. 628,286, dated July 4,1899.

To @ZZ whom it may concern:

Be it known that I, FELIX SOHANZ, a citizen of the United States,residing at Fort Wayne, in the county of Allen and State of Indiana,have invented a new and useful Photographic-Light Stand, of which thefollowing is a specication. r

This invention relates to an improved photographic-light stand designedfor illuminating the subject to be photographed.

The main and primary object of the invention is to provide a new and useful construction of photographic-light stand especially adapted foruse in connection with acetylene gas and having means for completelycontrolling the quantity, intensity, and shade effect of the light, sothat a subject can be photographed under any condition of light andshade desired. With this end in View the invention, while displacing theordinary Hash-light apparatus, has a much wider range of use, as thesame provides for a continuous light absolutely under the control of thephotographer to place the desired light on the subject, While at thesame time shielding or shading the lens of the camera from unduereflection. v

With these and other objectsin view,'which will readily appear as thenature of the invention is better understood, the same consists in thenovel construction, combination,l and arrangement of parts hereinaftermore fully described, illustrated, and claimed.

Vhile the essential and characteristic features of the invention arenecessarily susceptible of modification, still the preferred embodimentof the invention is illustrated in the accompanying drawings, in which-Figure l is aperspective view of a photographic-light stand embodyingthe improvements contemplated by the present invention. Fig. 2 is atopplan view thereof, showing in dotted lines the axial adjustment of someof the light-shades. in perspective of a section of one of thehorizontal cross-pipes and the adjustable lightshades fitted thereto.Fig. 4 is a detail sectional view of one of the light-shades,showin gits pivotal connection with the burner-j et sup- 5o porting the same.

Fig. 3 is a detail" Serial No. 696,289. (No model.)

Referring to the accompanying drawings, the numeral l designates thebase or rest of the apparatus, from which arises an upright tubularstand 2, the upper open end of which adjustably receives therein thevertically-adjustable supporting-rod 3, which is held fast in itsadjusted position by means of the setscrew 4, mounted in one side of thestandard near its upper end and preferably provided with ahandle 5 forconvenient manipulation.

The vertically-adj ustable supporting-rod 3 of the stand has coupledonto its upper end a piping framework 6, which is made in any desiredsize, according to the required use of the stand, and this pipingframework is preferably made of ordinary gas-piping and essentiallycomprises the main upright central distributing-pipe 7, provided atspaced intervals with horizontal oppositelyextending coupling branchesS, having controlling or stop cocks 9 therein, and the horizontal crossor burner pipes 10,*c0upled at their inner ends to the said branches 8.The cross or burnerpipes lO extend horizontally from opposite sides ofthe central upright distributing-pipe 7, and each pair of the alinedpipes 10 constitutes what may be properly termed a cross-pipe, as thesame project from opposite sides of the distributing-pipe 7 andintersect therewith. The separate spaced cross-pipes are arranged indifferent horizontal planes one above the other, and in order to disposethese pipes in a step series in different Vvertical planes the portionsof the central distributing-pipe 7 between the separate cross-pipes areformed with lateral Oifsets 1l, as 'plainly illustrated in" Fig. 1 ofthe drawings'. Y'

By reason of the specific construction of the piping framework 6 suchframework necessarily covers a large'light area., and the properblending and gradation of the light is effected through the peculiardisposition of the cross-pipes l0 in different horizontal and verticalplanes, and in carrying out this feature of the invention I preferablyconstruct the uppermost cross-armlO of a greater length than the othercross-arms, as plainly illustrated in Fig. 2 of the drawings.

vided with a plurality of upwardly-disposed burner-jets 12, and each ofthese burner-jets supports for axial adjustment thereon an L-shapedlight-shade 13. The light-shade 13 for each burner-jet 12 is formed witha Vertical shield-plate 1l, having bent at right angles from its loweredge a horizontal base-flange 15, provided therein with a pivot-openingl0, which receives therethrough the burner-jet 12, supporting the shade.By mounting each L-shaped shade in this manner the vertical shield-plate14 thereof is disposed at one side of the vertical plane of theburner-jet and maybe turned in an axial plane around said burner-jet inany direction to provide for shielding the lens of the camera from thelight.

As the vertical shield-plate 14 of each shade will lie in a planebetween the camera-lens and the burner-jet the side of said shieldplatenext to or facing the burner-jet maybe utilized for reilecting purposes,and to provide for this such side of the shield-plate of each shade iscovered with white enamel or other equivalent reiiecting-surface 17.

In order to facilitate the adjustment of all of the light-shades 13 oneach section or member of the cross-pipe 10, such shades are connectedtogether by a common connecting-rod 18, which rod is arranged parallelwith the cross-pipe section and passes beneath and ispivotallyconnected, as at 19, to the horizontal base-flanges 15 of theseveral shades. By reason of thus connecting the several lightshades oneach section of each cross-pipe 10 the adjustment or axial movement ofone shade will provide for the corresponding or simultaneous adjustmentof all the other shades coupled therewith. A proper adjustment of thelight-shades on the different crosspipes will provide for shielding thecameralens from the light, while at the same time concentrating thelight upon and around the subject to the very best possible advantage.

Near its lower end the central distributingpipe 7 of the pipingframework has coupled thereto a feed-pipe branch 19, provided with acut-oif cock 20, which serves to cut of the gas from the entire pipingframework 6 when desired, and which is also provided in advance of thecut-off cock 20 with a single burner-jet 21, which may be used to lightnp the room when the gas is cut off from the piping framework. Thisburner-jet 21 is also fitted with one of the light-shades 13, previouslydescribed. At this point it may be observed that the stop-cocks 9 may bemanipulated to cut off the gas from any one or more of the oppositesections of the cross-pipes 10, thereby enabling the photographer tocontrol his light to any desired degree and also to produce almost anyshade effect.

As the apparatus is especially designed to be used with acetylene orequivalent gas, giving a proper light for photographic purposes, thefeed-pipe brauch 19 has fitted thereto a gas-supply tube 23, leadingfrom a suitable I acetylene-gas generator 24.

From the foregoing it is thought that the construction, operation, andmany advantages ot' the herein-described light-stand will be readilyapparent to those skilled in the art without further description, and itwill be understood that any changes in the form, proportion, and theminor details of construction may be resorted to without departing fromthe principle or sacrificing any ot the advantages of this invention.

Having thus described the invention, what is claimed, and desired to besecured by Letters Patent, is
